Lightme - Logbook is a clean and powerful tool to record and keep track of your rolls, shots, developments, and all the gear that revolves around shooting film — from 35mm to medium and large format. The idea behind it is simple: logging a shot should take seconds, not steal time from actually shooting. Lightme pairs a beautiful, immediate interface with enough depth and flexibility to fit any workflow, whether you shoot a couple of rolls a year or fill several large format holders in an afternoon. LOGGING, EFFORTLESSLY • Log a shot in seconds: aperture, shutter speed, focal length, filters, bellows correction, measured EV, notes and more • Log straight from your wrist with the companion Apple Watch app, with Siri and Shortcuts, or from the home screen and lock screen widgets • Together with the Lightme Lightmeter app, your meter readings can prefill a new shot automatically • Every shot can carry a location and address, a preview photo, and later its final scan, plus a star rating ROLLS, SHEETS AND DEVELOPMENTS • Track rolls from loading to unloading, with film stocks from a growing database and a processing pipeline: waiting for development, off to the lab, back from the lab, to be scanned, scanned • Keep detailed development notes — developer, dilution, time, temperature, agitation — for rolls and single sheets alike, including push/pull (N+ / N-) development • Add post-development notes and a photo of the final result to rolls, sheets and individual shots YOUR GEAR, ORGANIZED • Cameras and lenses with nicknames, formats (including custom formats you define), pinhole and bellows flags, custom shutter speeds and selectable shutter step sizes • Roll film backs and lens filters with their exposure compensation • Film holders and backs can be marked as compatible with specific cameras, and everything is searchable from a single bar LARGE FORMAT, COVERED • Keep track of your film holders with three states — unloaded, loaded and exposed — always knowing which film is inside each one • Group holders together and follow every sheet from exposure through development INSIGHTS FROM YOUR DATA • Build and save custom queries, filtering by date (fixed or rolling windows), camera, lens, film stock, format, ISO, aperture, shutter speed, focal length and notes • Visualize results with histograms — by camera, lens, film stock, shutter speed, aperture, focal length, ISO, format, rating or hour of the day — alongside aggregate stats like mean aperture and average exposure • Save the queries you use most and re-run them anytime YOUR DATA, YOURS • Everything syncs privately through iCloud across your iPhone and iPad • Export any selection of data as CSV or JSON, or as a beautifully formatted PDF with customizable columns and a contact-sheet mode, bundled with your images in a single ZIP • Batch-write shooting metadata (EXIF) onto your scans — for a whole roll at once, or by matching files from the Files app • Viewing and exporting your data is free, forever; adding and editing is unlocked with a one-time purchase or a subscription AND MORE • Full-text search, favourites and an archive to keep things tidy • Available in English, Italian, Spanish, Japanese and Simplified Chinese • A roadmap of what's coming next lives right in the app — new very cool features are on the way :) If you have any suggestion or issue, write me at lightme.apps@gmail.com Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
